It seems that there are people out there looking to modify or "fix" trucks in a way that is unwise and unsafe. See the forum on the guy that put pneumatic tires on a cushion tire truck and was so proud that he was the only one who was smart enough to do it.
I once took a truck in trade where on intelligent "mechanic" took out every metric fitting and brazed an American SAE fitting to each one and then changed all of the hoses.
I guess I'm just overloaded with seeing all of the Mickey Mouse work that people do under the guise of saving money for themselves or their employer.
